关于此工具的常见问题解答。

Healthy direct-to-consumer (DTC) e-commerce brands typically target net profit margins between 15% and 25% after all ad spend and fulfillment costs.
Return on Ad Spend (ROAS) indicates marketing efficiency. If your gross margin is 50%, you need a minimum ROAS of 2.0x just to break even on advertising.
